rust-agents

Rust strategic architect specializing in type-driven design, domain modeling, workspace architecture, and compile-time safety patterns. Use PROACTIVELY when starting projects, designing type hierarchies, making architectural decisions, or implementing state machines with typestate pattern.

Rust developer specializing in idiomatic code, ownership patterns, error handling, and daily feature implementation. Use PROACTIVELY for implementing features, writing business logic, and refactoring code.

Rust testing specialist focused on comprehensive test coverage with nextest and criterion, test infrastructure, and quality assurance. Use PROACTIVELY when adding new functionality that requires tests, investigating test failures, or setting up test infrastructure. Also audits existing test suites for redundancy (duplicate tests, parametric overlap, property-test subsumption, placeholder smoke tests, oversized fixtures) to keep CI fast and signal high — runs the audit whenever validating existing code, before adding new tests to avoid duplication, or on explicit request ("audit tests", "reduce CI time", "cleanup test suite", "audit-mode").

Rust performance optimization specialist specializing in macOS optimizations (sccache, XProtect), profiling with flamegraph, benchmarking with criterion, and build speed improvements. Use when performance concerns are mentioned, slow code identified, build times need optimization, or macOS-specific optimization needed.

Rust security and maintenance specialist focused on cargo-deny, dependency management, vulnerability scanning, and secure coding practices. MUST BE USED for unsafe code blocks, authentication, authorization, cryptography, or external input validation.

Format documentation as an Obsidian knowledge base using the Zettelkasten method. Triggers on: 'obsidian', 'zettelkasten', 'knowledge base', 'create vault', 'obsidian notes', 'convert to obsidian', 'format as obsidian', 'cross-reference notes', 'map of content', 'MOC', 'atomic notes'. Produces interlinked notes with YAML properties, wikilinks, tags, callouts, and Maps of Content.

Write, structure, and maintain high-quality technical documentation using mdBook. Use when creating or editing mdBook projects, writing Rust/software project documentation, structuring SUMMARY.md, drafting chapters, API references, tutorials, architecture docs, or any mdBook-related content. Triggers on "mdbook", "documentation", "write docs", "technical writing", "book.toml", "SUMMARY.md", "chapter", "tutorial", "API reference", "architecture doc", "user guide", or "developer guide".

Architecture and code quality audit protocol for Rust projects. Activates expert knowledge across type safety, modularity, testability, readability, DRY, and async concurrency. Called by rust-arch-analyst at startup via Skill(...). When invoked directly as /arch-inspect [focus], the current session runs the audit without spawning subagents.

Orchestrate a continuous improvement cycle: spawn rust-live-tester for live testing, rust-researcher for dependency monitoring and research, rust-arch-analyst for code quality and architecture review, and rust-security-analyst for vulnerability scanning. Aggregates findings and produces a cycle summary.

Validate, format, and convert YAML/JSON files using fast-yaml (fy) tool. Triggers on: 'validate yaml', 'format yaml', 'lint yaml', 'check yaml syntax', 'convert yaml to json', 'convert json to yaml', 'yaml formatter', 'fix yaml formatting', 'json to yaml'. Supports bidirectional YAML ↔ JSON conversion, YAML 1.2.2 spec with parallel processing for batch operations.
